Answer:

Sodium Chloride has stronger ionic attraction than Potassium Chloride .

Explanation:

The radius of sodium ion = 102 pm

The radius of Potassium ion = 138 pm

From the given data , the radius of sodium ion is smaller than that of potassium ion .

Hence ,

Due to the smaller size of sodium ion , it will bind with stronger force of attraction with the chloride ion ,

as compared to potassium ion binding with the chloride ion , due to its larger size .

Hence ,

Sodium Chloride has stronger ionic attraction than Potassium Chloride .
